8-channel, Synchronous, 50V Boost, WLED Driver with I2C Interface

MP3371 and MP3372 are 3-30V input voltage, 8-channel, max 50mA/channel, synchronous, 50V Boost WLED Driver with I2C Interface and Phase Shift(MP3372). MP3371 and MP3372 support Analog/PWM/Mix dimming mode with Step-Slope Set Linear Smooth Dimming, they employ a low on-resistor MOSFET for higher efficiency and provides standard I2C digital interface for easy use, and MP3372 provides the Phase-shift function can effectively reduce the audible noise. Robust protections are available to guarantee safety operation including OCP, OVP, OTP, LED Short & Open and Diode Short protections. MP3371 and MP3372 are available in QFN-24 (4×4) package, designed for driving the white LED arrays as backlighting.
